France will not allow threats to weaken its resolve against terrorism, President François Hollande has vowed, reports the Belfast Telegraph.
He spoke out on Monday, hours after Islamic State released a video showing the extremists who carried out the November 13 attacks in Paris training, beheading and shooting captives in territory controlled by the group.
He said that it was because of the threat that he is asking to keep France in a state of emergency.
Mr Hollande imposed the state of emergency just after the November attacks which left 130 dead in the capital, allowing border checks, warrantless searches and house arrest without a court order.
The primarily French-language footage released on Sunday was apparently filmed in IS territory before the attackers slipped back into Europe.
The 17-minute video shows the extent of the planning that went into the multiple attacks in Paris, which French authorities have said from the beginning were organised in Syria.
The video was provided online by the Site Intelligence Group, which monitors jihadi websites, and in it IS - also known as Daesh - also threatens to attack Britain.
All nine militants seen in the video died in the Paris attacks or their aftermath. Seven of the attackers - four from Belgium and three from France - spoke fluent French. The two others - identified by their noms de guerre as Iraqis - spoke in Arabic.
Seven of the militants, including a 20-year-old who was the youngest of the group, were filmed standing behind bound captives, described as "apostates", who were either beheaded or shot.
"Soon on the Champs-Elysées," says Samy Amimour, who was raised in a Paris suburb near the French national stadium, as he holds a captive's head aloft.
